“…Other options for removing dissolved methane from effluents include oxidation of the effluent stream in a special reactor, the use of appropriately constructed biofilters or a downflow hanging sponge (DHS) reactor, or stripping and vacuuming. However, these are also associated with large energy inputs and low efficiency [136][137][138]. An interesting alternative for the removal of methane from wastewater streams may be hydraulic spray nozzles, which have demonstrated an efficiency of approximately 82% in removing methane from wastewater streams [136].…”

Brewery (BW) and dairy (DW) wastewater are two types of agro-industrial wastewater that are generated in large amounts and, therefore, should be treated effectively and in an environmentally beneficial manner. Both these wastewater types are characterized by a high COD, BOD5, and nutrient content, and conventional wastewater treatment methods such as an activated sludge process may prove to be inefficient due to the possibility of foaming, large biomass production, low activity at low temperatures, and risk of overloading the reactor with a load of organic pollutants. In the context of the described difficulties, anaerobic processes seem to be the best alternative. An interesting research area is the co-digestion of these wastewaters. However, this research direction, so far, has not been frequently reported. Given the gap in the current knowledge, this literature review aims to assess the possibility of BW and DW digestion in anaerobic reactors and provide up-to-date data on the post-treatment methods of effluent generated after the anaerobic digestion process. Despite numerous advantages, anaerobic treatment often requires post-effluent treatment to complete the treatment cycle.

“…(2) Treatment cost The treatment cost of SS and RM is high, including the pretreatment, transportation, storage, and subsequent utilization, which increases the economic burden of TES technology's application [110][111][112]. In 2021, the cost of SS collection and treatment services in cities around the world varied significantly, with costs ranging from as low as 0.1 USD/m 3 to as high as 16 USD/m 3 [113]. RM costs 11.08 USD/ton, and the accumulation and storage of RM comes with a significant maintenance fee [7].…”

Sewage sludge and red mud, as common industrial waste, have become a research hotspot in the field of achieving carbon peaking and carbon neutrality, reducing carbon emissions, and solving environmental problems. However, their treatment and disposal have always been a difficult problem in the environmental field. Utilizing these two materials for thermal energy storage can not only improve energy utilization efficiency but also further reduce carbon emissions during their treatment process, providing a new approach for sustainable development in the industrial sector. This article summarizes the research progress for the resource recovery of sewage sludge and red mud for direct thermal energy recovery and composite phase change energy storage. After proper treatment, sludge and red mud can be directly used as energy storage materials. In addition, sludge and red mud can be combined with phase change materials to prepare composite materials with an excellent energy storage performance. This composite has broad application prospects in fields such as solar energy utilization and building energy efficiency. However, there are still some challenges and issues in this resource recovery and utilization, such as potential environmental pollution during the treatment process, the long-term stability of energy storage materials, and cost-effectiveness, which require further research and resolution. The purpose of this paper is to evaluate the potential of sewage sludge and red mud as energy storage materials, to explore their feasibility and advantages in practical applications, and to reveal the research progress, technical challenges, and future development directions of these two materials in the field of thermal energy storage.
